From 37282f8fc135a16ff36e2afe0de907cbde531ed0 Mon Sep 17 00:00:00 2001 From: Damien George Date: Fri, 13 Oct 2017 20:01:57 +1100 Subject: extmod/uos_dupterm: Update uos.dupterm() and helper funcs to have index. The uos.dupterm() signature and behaviour is updated to reflect the latest enhancements in the docs. It has minor backwards incompatibility in that it no longer accepts zero arguments. The dupterm_rx helper function is moved from esp8266 to extmod and generalised to support multiple dupterm slots. A port can specify multiple slots by defining the MICROPY_PY_OS_DUPTERM config macro to an integer, being the number of slots it wants to have; 0 means to disable the dupterm feature altogether. The unix and esp8266 ports are updated to work with the new interface and are otherwise unchanged with respect to functionality. --- py/runtime.c | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'py/runtime.c') diff --git a/py/runtime.c b/py/runtime.c index 069548deb..17e5d235c 100644 --- a/py/runtime.c +++ b/py/runtime.c @@ -102,6 +102,13 @@ void mp_init(void) { MP_STATE_VM(mp_module_builtins_override_dict) = NULL; #endif + #if MICROPY_PY_OS_DUPTERM + for (size_t i = 0; i < MICROPY_PY_OS_DUPTERM; ++i) { + MP_STATE_VM(dupterm_objs[i]) = MP_OBJ_NULL; + } + MP_STATE_VM(dupterm_arr_obj) = MP_OBJ_NULL; + #endif + #if MICROPY_FSUSERMOUNT // zero out the pointers to the user-mounted devices memset(MP_STATE_VM(fs_user_mount), 0, sizeof(MP_STATE_VM(fs_user_mount))); -- cgit v1.2.3
